No, he's a known crank. see sci.crypt and then add him to your killfile

It's quite serious, but he's no cryptologist. He's a hapless crank, idiot,
and bullshitter.

He knows nothing, and nothing of the kind

For anyone else who's reading this thread, the way timestamps are handled
today is via a trusted third party. They stamp and digitally sign your file
and then you have something that can stand up in court, unlike Ada Cripple's
anything.

This doesn't guarantee the time stamp. You can always set your clock to
whatever you like before you sign.

No, it's something that real cryptographers and serious consumers of
cryptographic services already know how to deal with. There's infrastructure
set up for this already.

You, crank, are an idiot.

Yes it does. But he can't write anything.
